GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 621,842, dated March 28, 1899.

Application filed January 3, 1896. Serial No. 674,268. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM A. MCGUIRE, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Oar Doors, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a partial view of one side of the interior of a car, showing my improvement.

Fig. 2 is a section on line 2 2 of Fig. 1. .Fig. 3 is an enlarged detail, being a partial horizontal section on line 3 3 of Fig. 1. Fig. 4is an enlarged detail showing the method of at tachment of the swiveled arms, and Fig. 5 is asectional detail showing a modified arrange- I ment.

In cars engaged in carrying. grain and gen' eral merchandise it is necessary to have inside doors to prevent loss of grain and to have such doors arranged so as to interfere as little as possible with furniture, household goods, and other bulky freight when the car is used for transporting such articles. My grain-door for which I obtained Letters Patent some years ago was so superior in these respects to all others on the market that it has since gone into very extensive use, and I have since practically controlled the trade. There has recently arisen, however, a demand on some roads for a door so constructed that the guide-rods could be located so that the greater part of them would be practically flush with theinner face of the car-door posts, and to meet such demand is the object of my present invention.

I accomplish the above-described object by providing at each side of the door of the car guide-rods located so that the body or the portion between the ends of said rods is practically flush with the inner face of the cardoor posts, the rods at the lower ends being suitably shaped to receive the car-door supports, and by providing the car-door with arms which are swiveled to the upper portion thereof and are provided with perforations of sufficient size and shape to receive the guide-rods, thereby permittingthe door to be raised and lowered and to fit snugly in position.

To explain more fully, I will refer to the accompanying drawings, in which- 6 indicates the side wall of a car, 7 the floor, and 8 the roof; to the latter being suspended ahook 9, of the kind usually employed for retaining grain-car doors near the roof of the car.

10 indicates the car-door, and 11 12 the guide-rods. As best shown in Fig. 2, such guide-rods are inset, so that their intermediate portions are practically flush with the in nor face of the door-posts 13. At their upper ends the rods 11 12 are provided with hooks 14, as shown in Fig. 2. The lower extremities of the door-guiding rods 11 12 are provided with sockets 11, which when the door is in closed position receive the hereinafter-described perforated branches or extensions 15 and operate to prevent the displacement of the door ina vertical direction, as would be likely to occur by reason of the jar due to the rapid motion of the car. The sockets 11 further serve to permit said branches 15 to hang in a position nearer the side of the car, and consequently permit the car-door to fit more closely to the side of the car.

15 indicates arms, which are provided with laterall y-extendin g branches 15",having elongated perforations which are swiveled in brackets 16, adapted to be attached to the ends of the cardoor, as shown in Fig. 4, thus permitting the door to be rocked into a horizontal position when desired. As shown in Figs. 3 and 5, the upper ends of the branches 15 are bent or otherwise deflected or formed at an angle to the main portion of said branches to permit the branches to assume a vertical position when suspended from the rods 11 12, as shown in Fig. 2. The perforated arms 15 are preferably made by stamping out a blank and punching out the opening or perforation and then rounding or Working the blank to the proper size and shape in a drop-press, because in this way I avoid all welds and make a more reliable article. The brackets 16,

which support the arms 15, consist of forged or malleable cast sleeves or equivalent construction arranged to form hearings in which the arms 15 are swiveled, said sleeves having ears formed thereon for securely attaching the sleeves and the arms swiveled therein to the door.

In practice when the door is raised the perforations of the arms 15 move upward upon the guide-rods 11 12 until the branches 15 reach the hooks 14 when the door is swung to a horizontal position, its lower edge being caught by the hook 9. \Vhen the door is moved down and turned to a vertical position to close the doorway, as shown in Figs. 1 and 2, the branches 15 will move down the rods 11 12 and will hang vertically, their bent-over ends resting in the sockets 11.

Instead of forming the hooks 1i integral with the rods 11 12 they may be made sepa-' rate therefrom and suitably secured in position. A

In Fig. 5 I have shown a modified arrangement of the guide-rods, in such construction the door-post being grooved, the guide-rod being placed in such groove. By forming the perforations of the arms 15 at one side of the swiveling center of said arms they will embrace said rods when located as above described.

By the construction herein described the guide-rods may be inset, so as not to project materially into the car, and at the same time the door will fit properly across the doorway.

That which I claim as my invention, and de sire to secure by Letters Patent, is-- l. The combination with inset guide-rods attached to the car at each side of the dooropening and having their intermediate portions substantially flush with the door-posts,- of a door, arms swiveled thereto and provided with laterallyextending branches having elongated perforations receiving said guiderods, and sockets 11 at the lower ends of said guide-rods, substantially as described.

2. The combination with inset guide-rods attached to the car at each side of the dooropening, the intermediate portions of said guide-rods being substantially flush with the door-posts, of a door, and arms swiveled therein and provided with laterally extending branches having elongated perforations to receive said guide-rods, the upper ends of said branches being angularly arranged, and said guide-rods having sockets 11 at their lower ends, substantially as described.

3. In a ear-door, the combination with doorguiding rods arranged on opposite sides of the door-opening and flush with the doorposts, and having at theirlower ends sockets 11 and at their upper ends hooks 1-1, of a door having arms swiveled in its opposite sides and provided with laterally-extending perforated branches embracing said doorguiding rods, said branches seating in the sockets at the lower ends of said rods when the door is in closed position, and engaging the hooks at the upper ends of said rods when the door is open, and means to engage and support the free end of said door when in its open position, substantially as described.
